Port of the popular multi-OS N64 emulator, Mupen64, to the Nintendo Wii and Gamecube through the libOGC library. The emulator uses dynamic recompilation of the N64 machine code to PowerPC machine code and full hardware accelerated graphics to achieve (mostly) full speed emulation. Currently the emulator is in beta stage and can run many N64 ROMs at full speed in most cases.

Not64

Not64 is an "experimental modification" of Wii64. It forked from the "Beta 1.1 'Honey'" version and includes several fixes and additions.

Further Information

The emulator can be controlled with any combination of GC controllers, Classic Controllers, Wiimotes with Nunchuks and even just Wiimotes. See the included readme for details on the controls. You can load ROMs and saves from a FAT formatted SD or USB (details on the folders required are in the readme).

Developers

We don't want to discourage other people forking and working on the emulator; however, any unofficial builds must not be called "Wii64" or "Cube64" nor use the Wii64 or Cube64 logo in order to avoid confusion. For now, we're just releasing a snapshot of the source used to build Beta 1.1, but we're planning on updating the public repository with each commit we've made to our private repository so that everyone can see the progression of the code. This process will begin soon.

Video

Show FPS: Display the framerate in the top-left corner of the screen

Screen Mode: Select the aspect ratio of the display; 'Force 16:9' will pillar-box the in-game display

CPU Framebuffer: Enable for games which only draw directly to the framebuffer (this will only need to be set for some homebrew demos)

2xSaI Tex: Scale and Interpolate in-game textures (unstable on GC)

FB Textures: Enable framebuffer textures (necessary for some games to render everything correctly (e.g. Zelda Subscreen), but can impact performance; unstable on GC)

Input / Controls

Controls are now fully configurable so any button on your controller can be mapped

The controller configuration screen presents each N64 button and allows you to toggle through sources

There are 4 configuration slots for each type of controller

To load a different, previously saved configuration, select the slot, and click 'Load'

After configuring the controls as desired, select the slot, and click 'Save'

After saving different configurations to the slots, be sure to save your configs in the input tab of the settings frame

Clicking 'Next Pad' will cycle through the N64 controllers assigned

There is an option to invert the Y axis of the N64's analog stick; by default this is 'Normal Y'

The 'Menu Combo' configuration allows you to select a button combination to return to the menu

Configure Input: Select controllers to use in game

Configure Paks: Select which controller paks to use in which controllers

Save Support

There is native save support for the SDGecko, Front-SD, USB and Gamecube Memory Card

To save, you must have a directory named "/wii64/saves/" in the root directory
